Methyl Lactate → HCID 18619199, compound

Participants

Reaction Steps

To a mixture of 60 mg of 5-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-pyridone, 1.0 ml of tetrahydrofuran, 25 mg of methyl lactate, and 64 mg of triphenylphosphine, 123 mg of a 40% solution of diisopropyl azodicarboxylate in toluene, and the mixture was stirred for 2 hours at room temperature. The reaction solution was poured into water, and extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 20 mg of 5-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-{1-(methoxycarbonyl)ethoxy}pyridine [present compound 7-12].
